' COMBINED ooen nnn ens HnA'rme-s'rovn Be it known that I, LINCOLN HOWARD, a

yitizen of the United States, residing at Ralston, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in a Combined Coal and Gas Heating-Stove, of which the following is a specification.

The object sou ht in this invention to provide a stove that can be used for either. coal, artificial gas, ornatural gas, or that i can be used for coal at the same time intensifying the heat by theuse of the gas coked from the coal; 1

- I accomplish my object by the mechanism illustrated in the accompanying drawings, in which,-

Figure 1 is a sectional elevation of the entire device; Fig. 2 is a cross section of the device shown'at line {LL-17, Fig. 3 is an enlarged detail of the side of the magazine,

' broken away, and a gas ring seated therein forming a gas chamber; Fig. 4: is an elevation of Fig. 3, and Fig. 5 is a cross section of the magazine, broken away, and a segmental casting seated therein.

Similar letters refer to similar parts in the several views.

A is an inverted frusto-eonical base of the stove and B is afire pot therein of corresponding inverted frusto-conical shape.

C is the body of the stove.

' is a sheet iron extension of the body C.

D is a soft coal magazine for the double' purpose of holding coal and generating gas therefrom.

D] is a gas ring around the'bell of the magazine which forms the outer wall of a gas chamber; the bell of the magazine form ing theinner wall of the gas chamber or The bottom of the gas ring is provided with notches d (Zwhere it joins the bell of the magazine to permit the burning of the gas as it comes outof the gas chamber.

is a pipe extension to the passage cham ber formed by the magazine and segmental casting E. Said casting E is joined at the bottom to gas ring D and at the 'top to the underneath side of a support H which 'serves both as a magazine support and abafile plate. E is-aw pipe connected at the top with the top-ofthe stove and is seated in the magazine support, thus forming an'ex- Specification of Letters Patent.

tension of segmental casting 'E. The gas generated by the magazine passes through hole 6 into the passage chamber formed by Eand D and is conducted through said passage doWn into gas chamber d formed by D and D. From this chamber the gas is distributed out through notched burners 01 d These notched burners are spaced apart around the bottom of the entire gas ring. Pipe E is for the purpose of conducting cold air taken in through opening 0 down to the passage formed by E and D where it mixes with the gas before entering the gas chamber. I is a pipe through. which to introduce artificial or natural gas into the said burner when the stove is-not used for generating its own gas.

I is a plug to close own gas. When the stove is used exclusively for artificial or natural gas the plug I is removed from pipe I and screwed into hole 0 in the side of the magazine. J is a ring for extending the sheet iron drum or extension C of the stove; it also serves as a support for said magazine bafiie plate or support H. Said support H is fastened to extension ring J by bolts and is provided with three openings: one h, to make the passage continuous from pipe E to the passage formed by E and D; a second opening, h, throu hwhich fuel is supplied to the magazine and a third opening, k through which the smoke reaches smoke pipe K. p a

- L is a cap or lid to cover opening h, shown in Fig. 2; it is provided with a long lever or handle cast as a part thereof and is I pivoted to extension ring J at point J. p

M is a hopper throughwhich to convey gas therefrom, and provided with an aperture near its'top, a gas ringaround thebell of the magazine forming the outer wall ofa gas chamber, the bell of the magazine forming the inner wall of said. chamber, the gas ring notched to form burner openings at the bottom thereof, a segmental castingseated in the side of the magazine and spaced there'- a passage ;with

2. In a coal and as heating stove an inverted firusto-conica -:ho11ow base, a fire pot therein of corresponding inverted shape spaced therefrom, a stove pdy supported on said base, a magazine within sa1d b0dy having an aperture near its top communicating with a mixing chamber, a ring seated on the outside at the hell of the magazine spaced from the wallof the magazine to form there with a gas chamber and notched at the bottom to form burner openings, a segmental casting spaced outside from the magazine forming therewith a mixing chamber for the cold air entering at the top thereof and the gas entering the same from said magazine through. said aperture, a pipe entering said notched ring and aplug to insert in the outer end thereofwhen-sald magazine is generating its own gas, and adapted to be removed and screwed into said aperture near the top of the magazine'when said pipe .is connected with a supply of artificial or natural gas.

In testimony whereof I affix my signature in presence of two witnesses.

LINCOLN HOWARD.
